Rocks And Minerals Cont.

Front 1

What is the rock cycle?

Back 1

below earth's surface magma cools-igneous rock(intrusive), above earth's surface(volcanoes) igneous rock (extrusive)weathering, erosion, sediments, pressure/cementing, sedimentary rock, head and pressure metamorphic rock melts

Front 2

What is magma?

Back 2

molten rock inside the chamber of a volcano-with heat and pressure magma breaks through a crater in the earth's crust and turns to lava-cools=igneous rocks

Front 3

Example of Igneous Rock/Granite?

Back 3

Granite-forms underground, cools slowly, large crystals

Front 4

Example of Igneous Rocks/Basalt?

Back 4

extrusive igneous rock that cooled rapidly, dark colored, fine grained

Front 5

Example of Igneous Rock/Obsidian?

Back 5

also known as volcanic glass; was used by Native Americans as spearheads

Front 6

Example of Igneous Rock/Pumice?

Back 6

forms from the quick cooling foan on top of lava/ it is very light and porous (sponge-like appearance) may be used for pedicures.

Front 7

What is Metamorphic Rock?

Back 7

Metamorphic Rock is created when intense heat and pressure cause a sedimentary, igneous or other metamorphic rocks to change forms. This can occur when a rock is close to hot magma or when the folding and shifing of layers of earth put pressure on the rock.

Front 8

What is Metamorphic Rock/Slate?

Back 8

stated as shale with more hidden pressure, it becomes schist

Front 9

What is Metamorphic Rock/Marble?

Back 9

started as limestone

Front 10

What is Metamorphic Rock/Gneiss?

Back 10

started as granite; gneiss has distinct black and white stripes

Front 11

What is Metamorphic Rock/Schist?

Back 11

often started as shale, made of clay minerals
